104:31-35 Man's glory is fading; God's glory is everlasting: creatures change, but with the Creator there is no variableness. And if mediation on the glories of creation be so sweet to the soul, what greater glory appears to the enlightened mind, when contemplating the great work of redemption! There alone can a sinner perceive ground of confidence and joy in God. While he with pleasure upholds all, governs all, and rejoices in all his works, let our souls, touched by his grace, meditate on and praise him.

35. Those who refuse such a protector and withhold such a service mar the beauty of His works, and must perish from His presence.

Praise ye the Lord—The Psalm closes with an invocation of praise, the translation of a Hebrew phrase, which is used as an English word, "Hallelujah," and may have served the purpose of a chorus, as often in our psalmody, or to give fuller expression to the writer's emotions. It is peculiar to Psalms composed after the captivity, as "Selah" is to those of an earlier date.
